EU exit

Please note that, in the event of the UK leaving the EU without a negotiated agreement, some CAA website content and application forms may continue to carry the EASA logo or reference the EU or EASA rather than the UK CAA in the short term. These will be updated in due course following the UK’s departure from the EU. In the meantime, the guidance provided and the application forms accessed via the CAA website portal will continue to be valid.

Title:The Use of Leq as an Aircraft Noise Index
Description:The results of the public consultation on the proposal to replace the Noise and Number Index by Equivalent Continuous Sound Level are reviewed. Although there were many questions about the way in which Leq might be used, especially with regard to the distinction between day and night, there was general support for its adoption. Means for calculating Leq contours are discussed, as is the comparability of NNI and Leq values.
